The mortise box is the locking mechanism that sits inside the pocket, mortised into the edge of your door. If a mortise box option is not selected you will receive the Handleset trim (exterior and interior escutcheons with knob or lever choice along with necessary screw pack for installtion) and Cylinder ONLY.

If you require a mortise box you will need to determine your backset by measuring from the edge of the door to the center of the hole where the knob or lever is attached.

Choose "Keyed Alike" to use the same key on mulitple locks or "Keyed Differently" to ensure that multiple locks will require different keys. If you require us to key a lock the same as an existing key, please enter the key code in the custom keying box.

Please contact customer service for assitance with master keying or keying multiple manufacturers the same.
